Hello,
Yeap it should work fine for data (without PoE) as long as you have enough capacity to power all your modules.
Reference:
Therefore the information I found in the following link:
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps4324/product_data_sheet09186a00801f3dd9.html
Please read under Table 2.
The Cisco Catalyst 4500 E-Series offers a variety of power supplies and
accessories to meet the diverse needs of enterprise and service provider
customers. All available Cisco Catalyst 4500 Series power supplies can be
used for data-only deployments, which typically require just a few hundred
watts. For deployments that dictate support for PoE power, Cisco offers
several options.
The Cisco Catalyst 4500 E-Series offers AC power with several internal
supplies: 1000W (data only), 1400W (data only), 1300W (data and PoE), 2800W
(data and PoE), 4200W (data and PoE), and 6000W (data and PoE). When 5500W
or less are required, the 4200W power supply can provide 5500W while
protecting the chassis from a power or power-supply sub-unit failure. When
more than 5500W of redundant data and PoE are required for a Cisco Catalyst
4500 Series chassis in an AC-powered environment, Cisco offers an external
AC power shelf that houses two 2500-WAC power supplies. When two power
shelves are combined, they can produce 7500W-the remaining 2500W supply can
be used for N + 1 protection. All Cisco Catalyst 4500 AC power supplies are
single phase.
