Windows 7: power supply update

power supply update

I am wanting to upgrade my graphics card and to do so I need to change my power supply to a higher wattage unit. My current power supply exhausts air directly out the back of my tower. This new power supply which is a BFG 450 watt appears to suck in air from the back and exhaust the air through its fan on the bottom of the supply directly inside the case. In my way of thinking this would introduce more heat inside my tower. Is it typical for the higher wattage PSU's to exhaust inside the tower? Should I be concerned? Just seems to me that the power supply should be drawing air through the tower and exhaust out the back.

I'm not familiar with that PS, but some cases are designed to locate a PS in the bottom of the case, rather than on top as usual. The bottom designed case has a vent in the bottom to allow air to flow through. I would imagine that it is a matter of compatibility between the case and the PS.

After taking a very quick look on the BFG website, it appears that Beariot is correct, and that the bottom fan intakes, while the back fan exhausts. In that case, it would work in either the top or bottom location.

I don't know if it is that way by design or not, but I'd think you could get inside the PSU and turn that fan over to reverse the airflow direction. Maybe it was assembled incorrectly at the factory?

Back to Best Buy

Well that PS is now back at Best Buy. I would now appreciate recommendations for a PSU at the 450 to 500 watt range that would fit in a HP A6757c desktop. Sole purpose of updating is to allow me to install a mid range graphics card in a express x16 slot.

Seasonic 500 watt, with modular connectors. High quality respected manufacturer and the modular connectors make for a tidier installation:

Newegg.com - SeaSonic M12II 500 Bronze 500W ATX12V V2.2 / EPS12V 2.92 80 PLUS BRONZE Certified Modular Active PFC Power Supply - Power Supplies

The Corsair HX series is also good and I think they are all modular. I think there is a 520 watt model.

http://www.google.com/products/catal...340&sa=title#p

Seasonic also makes a 430 watt modular model, the M12II-430

Generally, Fortron aka FSP aka Sparkle also makes good units.

Whichever you choose, make sure it has enough connectors to meet your needs.

Budget is no more than a hundred bucks for the PS. Want a quality unit but only have Best Buy and Staples locally to purchase from. On line is always a option. Can you explain what modular means with regards to a power supply please
