I am planning to replace my current 300W PSU for a better 450W PSU.


My desktop is an 'hp a6010n' with the ATX-300GU. The reason I'm buying the new PSU is to upgrade to a higher wattage and be able to use my newly bought graphics card to its fullest potential. My graphic's card is this :


I'm just curious on if I can run my graphics card with the 'Raidmax Rhino Panther 450W ATX Power Supply' that I'm going to buy tomorrow. Please tell me if the power supply is good enough to run my graphics card with max settings with phsyx enabled. I want to be able to play modern games like Left for Dead 2 and Modern Warfare with max settings and phsyx enabled. Please reply. Thank you.

I would suggest staying away from Raidmax. The wattage should work, but with most power supplies, I recommend getting a unit with more than one 12V rail. I suggest, for power supply companies, going with Silverstone, Corsair, Thermaltake, Seasonic, PC Power, or OCZ. However, that card will not be good enough to play those games with max settings. For that, I suggest either a Radeon HD 5770 or better on the ATI side or a GTX 260 on the Nvidia lines. Obviously, better cards will offer better performance, so a Radeon 5850 will offer much better performance at high detail than a 5770

Rosewill PSUs are hit or miss for quality.

Here is an excellent deal:
[ Antec 1200 v3 | Gigabyte GA-890FXA-UD5 rev. 3.1 | AMD Phenom II x6 1090T (overclocked to 4GHz) | Corsair XMS3 4x4GB DDR3 1600 | COOLER MASTER Silent Pro 600W & Visiontek Juice Box 450W | SAMSUNG 470 Series 64GB SSD | WD Caviar Black 640GB & Samsung Spinpoint 2TB HDD | 2x XFX Radeon HD 5770 in Crossfire | SAMSUNG 22X DVD±RW | Microsoft Windows 7 Professional 64-bit]

Agreed with above, Raidmax is the PSU supplier you generally shy away from. Rosewill isn't on the short list of "most reliable PSUs" either.

Don't get hung up on the total wattage of a PSU. You are concerned with the "+12V" rail(s). Notice the 20 amp 12V+ rail on the Raidmax? That is just over half of the total power output of the unit (240 watts). Not a good thing.

Rosewill, 30 amps on the 12V+, but no PFC, and it is only ~65% efficient.

The Coolermaster is better, but misleading. Technically, you should be able to pull 36 amps combined from the 12V+ rails (18+18), but in reality it only supplies 324 watts total on the 12V rail or 27 amps total. Not great considering it only has slightly above 70% efficiency and no PFC.

My choice for a cheap PSU: http://www.newegg.com/Product/Product.aspx...N82E16817139008


While technically rated at 400 watts, look at the 12V rail, 30 amps. It is also 80+ certified.
