Power supply wattage

Hi Guys,:hello:
at my local store there is a good deal on a 450w power supply, i would just like to know if it is enough power to run my system that i am planning to build:
Mobo: ECS Elitegroup P55H-A2
CPU: intel core i7 870 2933 MHZ
GPU Nvidia GeForce GTS 450
RAM: 2 sticks of 4GB DDR3 Corsair
HDD: A regular SATA hdd
Drives: 1 DVD/CDRW combo drive
1 DVD RW drive
PCI cards: 32-bit soundcard
: 2 port usb 3.0 card
Other: 1 Front bay multicard reader which plugs into the usb plugs on the mobo
1 intel cpu cooling fan
2 in-case usb ports

will a 450w psu run this setup?
the psu calulator on www.thermaltake.outervision.com/ recommends that i have a minimum on a 334w power supply
Thanks :)

    You're planning to build that? Those components are old, you don't want to build a system like that now.

    But yes, they PSU should be fine.
  2. yeah 450 is minimum, i would go for a 500w

    im on a very tight budget of about $500 and as far as ive read that system should be able to run most of the newer games
  4. You can get a new system for $500. i3, HD7850 probably. That's what I'd do.
  5. What is the brand of the PSU? That is a much more important question. A good quality PSU will handle that fine but sub standard and you could be looking at a heap of trouble.

    I also have to agree with Finneous, this is a really out of date system.

    For a $500 dollar system you could try the build out of the system builder marathon $500 dollar gaming rig

    it is an intel processor.
    what components are outdated? the gpu? cpu? mobo? thanks

    isnt an i7 better than an i3 and is an hd7850 better than the gts450? thanks
  8. The CPU, GPU and Mobo are outdated, they are an older chipset, what we have recommended is the latest generation of intel processors.

    Being on the current chipset will enable you to upgrade in the future if you want to where as if you went with the old chipsets i7 you have no upgrade path.
  9. To give you an idea of what i mean by outdated.

    The suggested GPU is 5 tiers higher on Toms gaming GPU heirarchy. The current i3 is in the same grade as the older i7 870 but gives you an upgrade path, the G850 is slightly behind the i7 870 but is cheaper and also gives you an upgrade path.

    Thanks for the advice i really appreciate it, should i be looking at a mobo with a socket of 1155? and also what is the best gpu i would be able to get for about 150$ im on a really tight budget thanks
  11. Yes, socket 1155.

    Best to look at is probably the 7850 as suggested.

    If you take a look at my link a little up the page its a complete gaming system for $501, it should suit you nicely.

    hey mike what do you think about this setup?
    mobo: gigabyte GA-970A-UD3
    GPU: XFX radeon HD 6850
    CPU: AMB FX 4170 4.2GHz?
    thanks
  13. Personally i dislike amd, i find it very difficult to recommend them when so many Intel cpus out perform them. My recommendation is still with what i linked above.

    probably not what you want to hear but i hope it helps.

    i will decide on those 3 things later, if i were to go with the amd setup would the 450w power supply still work?
  15. From what i recall the 4170 has quite a high power draw compared to the intel chip.

    The PSU could probably handle it but don't take my word for granted.

    If it was me personally id stick with the intel chip and with that you'd be fine.
