Interesting I hadn't seen the HX450, it's new I think, the spec page is wrong for it, it should read:
•Supports the latest ATX12V v2.2 standard and is backwards compatible with ATX12V 2.01 systems.
•Ultra-quiet 120mm double ball-bearing fan delivers excellent airflow at an exceptionally low noise level by varying the RPM in response to temperature.
•Double-forward switching circuitry design offers maximum efficiency, up to 85% under wide load range.
•99% Active Power Factor Correction provides clean and reliable power to your system.
•Universal AC input 90~264V automatically scans and detects the correct voltage. No more hassle of flipping that tiny red switch!
•Dedicated single +12V rail offers maximum compatibility with latest components.
•Over Current/Voltage/Power Protection, Under Voltage Protection, and Short Circuit Protection provide maximum safety to your critical system components.
•High quality Japanese capacitors provide uncompromised performance and reliability.
•Auto switching circuitry provides universal AC input 90-264V
•Standard ATX PS/2 size: 5.9"(W) x 3.4"(H) X 5.9"(L); 150mm(W) x 86mm(H) x 150mm(L)
•MTBF: 100,000 Hours
•Safety Approvals: UL, CUL, CE, CB, FCC Class B, TÜV, CCC, C-tick.
Note the efficiency is upto 85% not upto 80%, I think the product spec page is taken from the HX520/HX620 which are seasonic not Channel well tech.
If it's another Channel well like the HX750 and HX850 it will be a seriously stable PSU.
thanks for the replies.... I was also concidering the tri core for a little more power but not as expensive as a quad.
also i was aiming for about a 500-550watt PSU incase a GFX is later put in... but i trust Corsair build solid psu's so i figured the 450 would be ok?
can i ask why most people have avoided the Samsung T220? something i dont know about it?
The 450W Corair HX is undoubtedly a good PSU, though for your budget the VX or the PC Power & cooling 420 would be a better choice. However, if you have your heart set on the HX 450W then you will be getting a good PSU. Also, any of those PSUs will be barely tested by the PC specifications suggested above, you could happily add a mid-range graphics card to it later and it will still run fine - even the 420W will be grand.
There is nothing wrong with the samsung T220. It is simply a bog standard TN panel monitor, no more no less - It will likely suit you fine for your applications.
However, I specified the more expensive Dell 2209WA for a couple of reasons:
-It uses an eIPS panel which is far higer quality than a TN (such as the T220) so it has much better image quality and viewing angles
-For your applications I judged that you would benefit more from a better monitor than a better CPU (as for the applications you allude to, such an upgrade will not give you much (if any) extra performance).
-Dell warranty is simply brilliant, if you have a problem with the monitor then dell come around the next day with a replacement monitor and exchange it on your doorstep - so you are never without a monitor.
Here is a good website that details the difference between the monitor panel types, the uses a version of IPS, the samsung uses a TN+ panel.
