Windows 7: Is This PSU good enough for a gaming rig?

What CPU and graphics card do you intend to use in your build?

The simplest thing to look at is the current available on the +12V rails. For example, the CIT PSU that you list has a total of 40A available on its two +12V rails. That marks it as a cheap "750W" supply. Here's a decent 550W PSU:

Newegg.com - CORSAIR CMPSU-550VX 550W ATX12V V2.2 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply - Power Supplies

from Corsair. It has 41A available on its single +12V rail. (Newegg doesn't do business in the UK, sadly.) My 750W PSU from PC Power & Cooling is rated at 60A on its +12V line.

It's common for people in forums such as this to be rather casual about advising people to spend a lot on components, especially PSUs. However, I don't think that you're going to get a good one for 30. You probably don't need an 200 one, but your choices will be better if you can afford 60.

That's bass ackwards from my experience. I find that people are very casual about advising folks spend lots of money on graphics cards, RAM, CPU, motherboards, then turn around and recommend a no-name, generic, budget PSU to power them.

I haven't been keeping statistics.

Many years ago, I used to watch Star Trek (tOS) reruns on one of the big independent NYC TV stations. I complained to a friend that I'd see some of the episodes over and over again. He had the same complaint. We compared notes: the ones he saw repeatedly were ones I hadn't seen since they were originally broadcast. This was on the same TV station.

My point? Perception is reality, I suppose.

I don't have much experience as other users on the forums, but i've built a Gaming PC, and it's complicated to choose the parts. The Performance of the PSU will not be as good if you were to buy a Cheap PSU. However go for other options such as XFX, Corsair, ect. Basicly good brands which are known. The case, doesn't really matter alot, but i've had this case. It's not very reliable as times goes pass bits and peices starts to eventually fall.

I am afraid I have to disagree with that. I think a good case, along with a good PSU, make up the foundation for a good computer. A good case will be sturdy and "true". By "true" I mean the corners will be exactly 90 and the straight lines will be straight. The corners will be reinforced. A sturdy and true case does not flex, twist, or warp when moved. This is important because a cheap, flimsy case will warp and this can cause extreme torque on the mounted motherboard resulting in stress fractures forming around the mounting screws - not good. It can also cause damaging torque on add-in cards which are mounted to the board, then secured to the case. A good case will not require you to remove both side panels to install a drive (instead it will use rails or removable bays). A good case will support multiple large (120mm or larger) fans and be designed to provide the best front to back air flow. A good case will provide easy access. The sheet metal will have rolled edges to prevent your blood getting all over the place from sliced knuckles. And a good case will have a washable, removable filter. A good case will support MANY years of upgrades.

That said, I do not support the use of flashing lights and a fancy facade. A fancy face is faddish, and will go out of style. Lights do nothing for performance, consume power, add heat, and do nothing for performance (worth repeating). A good case should sit discretely, and quietly out of the way, and not draw attention to itself - unless watching cases is your thing - I tend to pay attention to the monitors!

I like Antec cases - though most are steel, and tend to be heavy.

One word of caution. Many case retailers will "toss in" a PSU to make a case sale. Often these are good cases but generic, cheap supplies. Don't pass up a good case because it has a cheap supply. Just "toss out" the cheap supply (or use it as a spare for testing fans).

Digerati,

I do agree with you on the value of a quality case. For me, I find that the nicer cases (mine have been Antec), seem to do a great job with noise isolation as well. And the air filters have been extremely helpful in keeping the inside dirt and dust free...which keeps the fans and the air moving better. I never saw that much value in a good case until I tried one. Haven't done a cheap case since.

For whatever reason, I "rarely" upgrade any of my computers, but rather just build a whole new box each and every time and just keep the old one running, but performing a different task or given to another member of the family.

And I'm not a fan of lights and windows either. I like nice clean lines and I too pay far more attention to the monitor.

Good point. I just built a new system with an Antec Mini P180 case and if not for the power LED, you cannot tell it is running - of course the dead silent Mushkin 580W PSU helps too. This case has sound deadening materials layered in the panels, and the very slow moving 20mm "big boy" blow hole (on top of the case) fan barely moves (so no noise), but moves massive amounts of air keeping the system nice and cool.

Since many PCs are used in home theater configurations, fan noise has become an important issue. Many computers can easily have many fans (CPU, chipset, graphics card, PSU, and case fans) so controlling the noise is a challenge. In an office, especially with multiple PCs, the fan noise can become a serious distraction.
