here are the requirements PSU wise o run your 5450....
http://www.amd.com/us/products/desktop/graphics/ati-rad...
short answer 400W recommended...so yes your old PSU was not enough from the other thread

now the new PSU your getting the 450w is fine to run that card...and from your other thread...the tech you called was incorrect....as long as you have a PCIe slot and a power supply capable of running the card...it will work.

The 5450 is a VERY low power consumption GPU. A typical system will draw less than 200 Watts.
REF: http://www.techspot.com/review/244-ati-radeon-hd-5450/p...
1) AMD's 400 watt req is because they have NO control over the quality of the PSU - some Junky 400 Watt PSUs really only have about 200 watt outputs after they warm up - Lousy power deregulation.
2) although your "old" PSU was rated at 250 Watts, two unk A) what is the true wattage delieverable at 40 C and B) what was the +12 V rail rating which in todays computers is far more important than the total.

A quality 450 Watt PSU should be good upto a 6870 GPU.
My I5-2500k OCed to 4.2, w/16 gigs ram, 2 SSDs, 2 HDDs, Blu-ray writer and a 6870 only draws 350 watts.

Added:: While I love my corsair PSUs, the VX line is apparently a cut below the cx line-up. While it is OK it is getting close to the lower end of Recommended PSUs.
Should be a good cost effective PSU for Kingston Deva

There's a known compatibility issue with graphics cards that have a PCI Express 2.1 x16 bus interface running on a motherboard that is based on PCI Express Base Specification, Revision 1.0a like yours is.

Buying a new PSU will not fix a compatibility problem.

Your motherboard is PCI Express Base Specification, Revision 1.0a. Your graphics card is PCI Express Base Specification, Revision 2.1. That's why your system powers on but you don't get any image on your display. In theory Revision 2.1 is suppose to be fully backward compatible with Revision 1.x but in practice this wasn't always the case.

There is a known compatibility problem between the two revisions. When the AMD Radeon HD 5000 Series cards were initially introduced to the market this incompatibility problem appeared on some motherboards that were based on the PCI Express Base Specification, Revision 1.0a and 1.1. Some motherboard manufacturers released a BIOS revision that fixed the problem but others didn't.
