Why Do You Need A Big Pc Case?

The main reason for that is usually the fact that it’s better to have a bigger case than a smaller one. Actually having a bigger case gives you more choices in what components you install, and the size of the chosen components won’t be limited by your computer case. Having any limits makes it harder to achieve the maximum performance level which you want.

Another problem with small cases is the fact that they are limited in space, thus not able to accommodate many components like bigger cases do. This will make you build your machine with fewer features and technologies compared to what you would be able to get if creating it inside a case that was designed for the fully equipped machine (this also means that without any limits). Also, smaller cases can’t typically house more powerful hardware like graphic cards made for extreme gamers or processors with higher TDP (Thermal Design Power).

If you do decide to buy a full tower case instead of midi or mini one then there won’t be any disadvantages – including price. However, today’s market offers us several types of computer cases so you should consider your needs and preferences in order to choose the right one.

A bigger case is always better than a smaller one because it gives you more freedom and many more choices when creating your computer, and it will also allow you to install components that would otherwise not be able to fit into cases that are smaller. Smaller cases can’t house as big of components because they take less space, meaning the technology won’t be as good compared to if you had built it in a full tower desktop pc case. Also, by having a bigger case you don’t have to worry about all the features being too limited for your needs. If you end up going with a smaller computer case, there is no point considering buying a bigger one at some other time since small cases typically aren’t upgradable.

Tips On How To Pick A Psu (Power Supply Unit) For Your New Computer

1. PSU “bang for your buck” – there is no easy answer

There isn’t a simple formula to determine the best bang for your buck when it comes to power supplies because it’s dependent on many factors: the number and type of devices you want to power (e.g., video card(s), drives), how efficient you want the system to be, what advanced features do you need (e.g., modular cabling), and finally price vs. performance.  There isn’t an easy rule that says “$X wattage or greater PSU is good enough”. You might get lucky and pick something that matches all of your requirements such that it doesn’t bottleneck overall system performance, but most likely it will end up being inadequate in some regard.

2. Real-world measurements of efficiency (not manufacturer’s claims)

Don’t rely on manufacturers’ marketing materials that tout the high power efficiency of their units; instead, find independent reviews on sites like JonnyGuru or HardOCP, where reviewers actually measure system power draw vs. AC input using an oscilloscope and special software (to ensure accuracy). Use these measurements to pick a PSU with decent efficiency, not the ones with high-efficiency ratings based on their own internal tests which are more reliable than manufacturers’ “advertorials”. Also be aware that different people have different standards for what is acceptable – for example, if one unit barely squeaks into 80PLUS “80 Plus” certification at full load, it may be unacceptable to another person who expects efficiency levels to be at least 85%. Here are some example measurements of what you can expect from various brands/models – take them as rough guidelines only: Seasonic SS-250SU: ~82%  Corsair CX430M: ~83% Enermax Modu87+: ~85.5% Antec True Power New TP-550: ~80.5%-90% Rosewill Photon 550W: 83%-88+%

3. Avoid modular PSUs if possible

Modular cabling is generally useful since it gives the user more flexibility for cable management by allowing unused cables to be disconnected, reducing clutter inside the and improving airflow. However, modular connectors add to the cost of manufacturing (around $0.50-$1.00 per modular cable, depending on how many pins are used in the connector). If you don’t need all of the cables that come pre-attached to a non-modular PSU, it’s better for your build quality and airflow if you buy a unit with “semi-modular” cabling where only some of the cables are attached. Alternatively, even if you need every one of those connectors eventually, it’s OK to get a higher wattage non-modular PSU instead so long as your current power draw is below 60% or 70% of its rated maximum load (more than enough headroom under peak conditions). Modular PSUs are a nice convenience, but not a necessity in most cases.

4. Consider the combined +12V rail

There are two types of power supplies: those that have multiple separate 12V rails and those that have a single large 12V rail for the entire unit. In general, it’s better to get a PSU where all of its available power is on a single 12V rail because then you don’t have to be careful about mixing/matching different devices when drawing from the same PSU – e.g., if you’re pulling 150W from one device and 50W from another from an inadequate power supply with multiple 12V rails, both devices may end up getting much less than what they need resulting in reduced performance or shorter system lifespan.  If you’re not careful, the latter can even lead to a system-wide meltdown triggered by one device drawing more than its share of power from one rail and thus increasing the load on that rail past what it can handle.

5. Don’t cheap out on your PSU; buy something decent

An average PSU is unlikely to bottleneck an expensive high-end modern gaming rig, but a poor quality unit may fail prematurely (or worse) which could take the whole system down with it (due to shorted/faulty component(s)). For example, I’ve seen PSUs that were advertised as “650 Watt” units delivering no more than 500 Watts of actual continuous power given their extremely low overall +12V rail voltage stability.  As another example, I’ve seen a brand name “550W” PSU with only one +12V rail that could barely put out 200W when two devices were drawing from it – not even enough power for a GTX 660 Ti system! Believe it or not, these wattages/PSUs exist and you may end up spending more money on something like an aftermarket cooler (for your CPU) or high-end video card (which tend to require powerful PSUs due to their high power draw) if you cheap out on the unit powering your system.

6. Know how much power you need; don’t assume

For example, many assume that 150W via the combined +12V rail is plenty of wattage with modern components.  While this might be true for some mid-range CPUs, high-end gaming systems with multiple GPUs/multiple SSDs/etc. may easily require more than 150W combined 12V power. If you’re unsure of what your system will pull under full load, I recommend getting a PSU with at least 200W combined 12V power to account for worst-case scenarios (e.g., overclocking).

7. Get more than one PCIe connector if you can

This is especially important if your PSU only has two 6+2 pin PCie connectors which are not enough to support SLI or CrossFireX setups even on more budget-conscious PSUs. For example, the Enermax Modu87+ 700W offers four 6+2 pin PCie connectors that will support two mid-range GPUs in SLI/CrossFireX without any problems.  On the other hand, this same PSU only comes with a single 20+4 pin PCie connector which is probably not enough to handle most high-end CPUs on the market today (e.g., Intel Haswell i7-4770K, AMD FX-9590) unless paired with a modular unit.  For example, the S12II 620 Bronze from FSP is a great non-modular 80 Plus PSU that has six 6+2 pin PCie connectors on it which can support up to three mid/high-end GPUs in SLI/CrossFireX without getting into multi-rail territory or insane prices.

8. Consider cable lengths/number of connectors

Some older power supplies have very short cables which are problematic for larger cases with poor cable management design (i.e., lots of sharp bends).  Bad cable length can also contribute to overall system noise by causing power supply fans to ramp up in speed. Modern PSUs tend to have much longer cables which are usually more than long enough given today’s case designs.  You also want to have the proper number of connectors for your devices without having too many leftovers that go unused or wasting money on the wire you don’t need – e.g., Molex connectors are generally unnecessary these days unless you have a very old motherboard.

Common Mistakes When Buying A Biggest PC Case

When buying the Biggest PC Case, you have to make sure that you are fully aware of what it can offer. It is not enough that the biggest PC case you are going to buy has all its features working because there are others who might be having better features with them. So, here’s a list of common mistakes people make when they’re buying their Biggest PC Cases.

1. Asking For The Best Solely And Not Looking Into Their Budget

When you go out looking for the best cases without giving much thought to your budget, then more than half the time, you would end up shelling out money beyond your ability – or at least breaking your bank account in this regard. That said, before heading onto the market, sit down, make a list of what you are exactly looking for in your biggest PC case, and only after that begin looking around. You’ll find yourself within your price range without having to break your bank account which is the reason why most people end up shelling out more money than they actually had.

2. Not Looking Into The Size Of The Biggest PC Case Before Buying One

Knowing the size of the biggest PC case is definitely important because if it doesn’t fit or match with your tower, then you’re pretty much stuck with whatever other solution possible just to get things working as intended. If you don’t know how big or small a particular model can be, then go online and search based on its specification, and pictures shown on those sites should help you make a better decision.

3. Ignoring The Fans Of The Biggest PC Case You Might Need

When buying a Biggest PC Case, there are just some models that come with fans already installed and for this reason, it is important to find out if the model you’re going for has any or not – just so you can expect to have your fan needs to be covered from the get-go. If it’s lacking, adding an extra fan from your side might be a great idea especially when building a water-cooling system because having less resistance within the case itself would help things move along faster.

4. Choosing A Biggest PC Cases On Looks Alone Could Be Problematic

There no denying that best biggest pc cases look great and when you consider the build quality to price ratio, it’s definitely a steal. That said, depending on your individual needs and how you do things, having one with good looks but doesn’t offer much in terms of performance could be such a hassle – especially if going for that extra mile is something that you’re big on.

5. Not Buying A Biggest PC Case You Will Have An Enjoyable Experience With

At the end of the day, what matters most is whether or not a particular product brings a smile to your face because at times there are certain brands who tend to win over customers with their incredible customer support system which both starts from right after opening up the package till even years after. If this isn’t important, then you might want to consider buying the cheapest one out there because it doesn’t matter what happens later.

6. Not Making Sure The Fan Placement And Direction Is Suitable For Your Needs

There are just some brands that offer universal fan direction which means that any fan of yours can be installed in any given space without having to worry about the airflow not working out too well for your needs. If this isn’t something you find important, then feel free to ignore the fans and cooling system altogether – but if it’s something you definitely need, make sure you check on this before making a final decision.

7. Thinking That A Biggest PC Case Should Only Be Able To Carry Certain Type Of Mobo

When deciding on your biggest pc case, the first thing you should know is that any type of motherboard will fit in as long as it has ATX or m-ATX form factor. That said, there are a couple of the best huge computer cases that feature a changeable internal structure which means that if you want to switch from one platform to another, all you have to do is remove those panels and you’re good to go.

8. Not Taking Care Of The Cable Management System And Placement Of Internal Components Within The Biggest PC Case

If spending extra time on cable management isn’t something you care about or don’t think is important – then by all means just ignore this aspect but if knowing how everything looks inside your case makes a difference to the overall presentation of your machine, then it is best to consider this point.

9. Not Understanding Fan Power Connections And How To Place Them

When you’re spending money on a Biggest PC Cases that come with fans attached, make sure that you have reviewed its manual thoroughly so you know how the power connections are being made because if there are no clearly marked labels for the maximum wattage needed, then just assume it’s safe to go under or above – which can definitely cause damage to both fan and motherboard in question.

10. Choosing The Wrong Size And Type For Your Needs

Although cases have varying size options ranging from small ones similar in height with an optical drive bay only up to big slotted towers, what really matters before making a decision is what you want to put into the case in question. If you prefer having most of your components on top of the case, it might be a good idea to go with something taller but if vertical mounting isn’t an option or not preferred, make sure that you know beforehand which brands offer the best biggest pc case options for particular hardware.
